I went to the doctor two days ago because of a weird period, lower abdominal discomfort, PMS/pregnancy-like symptoms and it was past time for my annual. My biggest fear is the possibility of ectopic pregnancy since I've had a tubal ligation.
The doctor ordered a home pregnancy test before I went in and it was negative. He asked about my relationship and I told him I've been in a monogamous, co-habitating relationship for a year and a half. During the pelvic exam, it was excruciating when he palpated my right ovary and I've been in pain since then. He asked about my prescription coverage and wrote prescriptions for two antibiotics to be used consecutively. He said that if that doesn't clear it up, he'll do an ultrasound in three weeks. He didn't do any further testing besides a pap.
Is it normal and fine to prescribe antibiotics as a way to diagnose an infection, or is it so conclusive that I have an infection that he didn't need to actually test for it?
How long is it supposed to take before the antibiotics start working? I've been in constant pain since the exam, and it's getting worse instead of better. Since yesterday, I've been having clear discharge that's tinged with fresh blood. It hurts worse when I walk around and I spend all my time at work on my feet. I'm supposed to go to work tonight, but I really just want to go to the ER. What should I do?
ETA: I tested negative for any infections six months ago, but I wonder if infection from recent anal activity with my partner could be a possibility.
